Adding a real subwoofer w/amp to your Mach-E

[Buh-Bye Tesla]

Not the most popular accessory, but I added the storage trays over the sub. Thought they might rattle or block the sound a bit but no issues. Don’t think I’d ever need the cargo cover lowered anyway.

Where do those storage trays come from? I just had my subwoofer installed at Cartoys since I'm not up to doing that these days. I need to cover it back up now, and will probably put strips of wood with velcro on each side.

Thank you for that info. Does the bottom of the trays sit at the same height as the floor in the lower level, I'm wondering if it would clear my subwoofer.

Yes I’d say it does since it’s resting on the foam.

UPDATE 04/07/24:

For the Keyloc, did you just connect the power for it from the wire that you ran for the amp, or did you do a whole new wire for it from the battery? I have the Keyloc and a Kicker 51SH10 waiting to be installed, I might do it this weekend, thank you for all the info on here!

Just used the power that I already have going to the sub. No need to run a separate line just for that.

Thank you! That is what I thought, but just making sure.

Hi folks, I’m hoping to install a subwoofer but without cutting or tapping into any wires so the mod is 100% reversible.

Could anyone confirm that this is the same connector that’s present in the subwoofer speaker assembly?

Looks like the same connector but I would think unless you actually try it, you would not know for sure.

For those doing the easy method, here’s my notes for my 24 kicker install:

remove 2 latches back panel: T25
remove 2 bolts lower back panel: 8mm

Mach E:
Subwoofer
Green/Violet +
Gray -

12v outlet:
Purple Power
Green Ground

Kicker Harness Wires:
Solid white and grey tie together to Mach E green violet +

White and grey with black stripe tie together to Mach E Gray -

Would it be possible to find a male plug (I assume male) to unplug the 12v accessory jack and connect to the plug in the car. I don't need the rear accessory jack.

I installed the JL Audio PowerWedge+ ACS110LG-TW1 after finding a sweet Open Box deal on SonicElectronix.com. If anyone ever dents or smashs the grille it pops out easily (no power tools required) and you can straighten it out.

I used this wiring kit and it's 100% copper wire, not CCA. https://a.co/d/0eeagKU6

The OEM subwoofer wires have different colors in my '25 MME GT but that didn't cause any issues.

Routing the power cable through the firewall was easy - after determining the rubber grommet had 2 layers to puncture. I sealed the "outside" grommet layer with black RTV afterwards.

It sounds great! Thanks @markboris for the awesome write-up and all of your follow-up posts.

To follow up on this, it took me a while to get all the parts and tools needed, but I can confirm that this is indeed the right connector. Tips for anyone who wants to use it:
- You’ll need an “open barrel” crimping tool.
- Make sure the inner white plastic part sits all the way towards the back of the connector, otherwise the female plug won’t latch. If the 2 connectors don’t click-in easily, the interior white plastic part isn't pushed deep enough.

This shows the correct final position of the inner white plastic part:

Also, here’s a reference image of how the OEM subwoofer connector is wired (black is negative, green is positive) you want to match that layout.

Finally, I’m sharing some notes on how I installed a Kicker HS8 in my 2025 Premium with B&O:
- The connector terminals were crimped directly to the gray signal wires.
- White signal wires were left disconnected.
- Have to use the +12V Auto Turn On mode and connect the blue wire to +12V, otherwise the subwoofer won’t turn on.
- I used this cigarette lighter connector: https://a.co/d/0cWmQVZX
- Input level: Hi
- Phase: 0°
- Bass boost: max
- Crossover: 80 Hz (around the 11 o’clock position)
- Gain: slightly below the second tick mark (around the 10 o’clock position)

All in all, I’m quite happy with the HS8. It blends nicely with the OEM sound system while still being clearly noticeable. Recommended!

@markboris and others with the Keyloc, when tuning which db test tone did you use? 0db, -5db or -10db?

Also, do you remove eq (beosonic to flat) and put it in stereo or surround (if that makes any difference to the curves)?

I'm a little late to the party, but I just picked myself up the JL audio 10" power wedge and bass control knob!

I already prepped the trunk last year with dynamat in anticipation for the sub. Can't wait for the weather to get nicer so I can work on this project.

Question for Mark and anyone else who has added the kicker keyloc device-- is it worth the $150?

Edit: I'm also looking at This amp to power the stock B&O door speakers. Would this be a good choice or are there better options for the $?
